Appendix: Drawings Revision History December 1997 227 483 02-B SA(e)-98.05 Initial Release SW Version 4 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 5 1. General Introduction CardioServ Semi-Automatic and Manual There are 2 CardioServ models: the semi-automatic and the manual defibrillator. Both models are available with a pacemaker and SpO2. The manual CardioServ is a defibrillator designed to deliver synchronized and unsynchronized shocks. This requires the user to trigger capacitor charging and shock delivery manually. The semi-automatic defibrillator is equipped with analysis software, which monitors the ECG for arrhythmias (fibrillation and ventricular tachycardia). When the analysis is started by pressing a key the ECG is analyzed. If the result of the analysis is positive, the capacitor is charged to the preselected energy level. The semiautomatic operating mode can be terminated by pressing a key or inserting the dongle. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH 227 483 02-B SA(e)-98.05 CardioServ V.4 Servicing Instructions Page 6 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 7 2.

Functional Description The Therapy System CardioServ comprises a defibrillator, a monitor ( LC display 240 * 320 pixels ), a printer and a power supply unit. These components are arranged in a casing. It is a compact unit, which can also be implemented using a 230-V power supply system, even without a battery. The unit has a pulsed 140-mA standard charge for the battery. Additional versions available have an external pacemaker and an SpO2 module, separately or combined. The Defi is switched on by turning the rotary switch to position ECG or energy levels automatic sequence 2 ... 360 J. Following a self-test, which tests - RAM data store - ROM program memory - Watchdog / Reset - EEPROM permanent memory - Display all Pixels on / off - Time base of internal quartz crystal - Energy charge from last shock - Defective charge or Defib keys - Position of energy selector switch - Connected electrodes - Pacemaker - SpO2 the Defi is ready for operation. If an error arises, depending on the severity of the error, the Defi is either on standby or not. Serious errors are watchdog, ROM or RAM errors. In the case of minor errors, an error message appears, but the instrument can be rendered operative by pressing a key. The Defi shock is delivered via exchangeable paddles. This permits the use of different electrodes, i.e., in addition to conventional electrodes, large-surface adhesive electrodes or internal electrodes, for example. Adhesive electrodes are used for the pacemaker. The CardioServ also has Start and Trigger buttons on the instrument. The charge operation is actuated with the Charge key on the apex electrode (for internal and adhesive electrodes on the instrument). During the charge operation, the accumulation of energy is registered and when the selected energy level has been reached the energy to be released appears on the display. An acoustic and visual display on the monitor indicates the configured energy level has been reached. When the battery is fully charged or with linepower operation, charging at 360 J should take about 8 s. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 12 The buttons on both electrodes are pressed to trigger the defibrillation pulse (safety two-hand operation). This means that the button on the apex electrode (or the corresponding one on the instrument) has two functions: - start the charge operation - trigger defibrillation (together with the Trigger button) The type of electrodes connected are recognized and, in the case of internal electrodes, the energy is automatically limited to 50 joules. Following defibrillation, the energy released is displayed on the screen for 6 seconds. Documentation output is by the printer. The defibrillator has three operating modes: * * * synchronized defibrillation (cardioversion) unsynchronized defibrillation (emergency therapy) semi-automatic (emergency service) Cardioversion (operating mode Sync) can proceed either via the paddles or a patient cable. The operating mode Sync appears on the display and Sync marks are superimposed on the display. Following cardioversion, for safety reasons, the CardioServ switches automatically over to the unsynchronized operating mode, i.e., before each cardioversion the instrument must be switched over to Sync. The Defi can be configured for semi-automatic operation in three ways: * As a semi-automatic instrument only (defibrillation only possible via analysis) * Semi-automatic instrument which can be toggled to manual mode by pressing a key * Semi-automatic instrument which can be reset into manual mode using a dongle ECG signal pick-up is possible via the paddles or ECG cable. ECG is output on the LCD display or by the built-in 50-mm printer. A safety device ensures the discharge of the storage capacitor in the following situations: - when defibrillation is not triggered 30 seconds after storage operation is complete, 0.2 seconds after triggering defibrillation, immediately after switching back the energy selector switch during or after storage, when the battery voltage drops below a certain level, when the selected energy level still has not been reached after 32 seconds. When switching to a higher energy level, the energy deficit is supplied by recharging. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 13 Pacemaker The pacemaker is a transthoracic pacemaker operating in the Demand and Fix mode. - Pulse width 40ms (20 ms) - The frequency is between 0...180 P/min (> 150 P/min only 20ms pulse width) - The current is between 0...200 mA - Adjustment is in 5-unit intervals. The pacemaker is operated using 6 keys on the control panel. One key switches the pacemaker on, one key changes the operating mode, the other keys are used to adjust the frequency and current. The defibrillator cannot be disabled as long as the pacemaker is switched on. The adhesive electrodes of the Defi are used to release a pulse. This ensures a rapid switch from defibrillator to pacemaker and back again. SpO2 SpO2 is based on one of the modules manufactured by Nellcor (MP204). This module is located on the PCB Analog and receives its power supply from the latter. Measurement of the oxygen saturation level and pulse frequency is made by this PCB. Pulse frequency from 0...250 P/min Saturation from 0...100% We display the plethysmogram, saturation level and, when selected, the pulse frequency instead of the HR. Control options: A battery charge check is performed under load application. The message charge battery on the display means the battery needs recharging. At least five discharges at maximum energy are still possible. (Possibly even considerably more) Performance check of defibrillation is performed by discharging into the integrated 50-ohm resistor. Monitoring battery charge via the connector for power cord by the yellow LED. If the battery is fully charged after 16 h, trickle charging ensues, the yellow LED is permanently lit up. The monitoring function of the CardioServ records and monitors the ECG and oxygen saturation level. The cardiac-action potentials are fed to the ECG preamplifier via a 5-wire patient cable. Selection can be made from 12 leads. The ECG curve is displayed on the LC screen with an illuminated background. The heart rate obtained from the ECG signal is continuously displayed on the screen. Communication between the user and the instrument is via the keyboard and the LC screen. These also serve to configure the default settings and functions (see Users Manual for further details). 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 14 The PCBs have the following functions: PCB Power Supply This PCB supplies the 16.5-V instrument power supply. 10 A can be supplied for short-term capacitor charging. It is a primary clock-rated wide-range power supply system. It operates from 85 .. 264 V, at 49 ... 65 Hz. It is protected by 2 fuses in the primary circuit. One on the PCB and one in the feed line. PCB Analog This PCB has several functional units. The first unit accepts the ECG signals (patient input) received via the patient cable from the patient. In accordance with its task, it is connected to the patient by a cable. It is thus constructed as an application component isolated from other circuit components and the circuit reference (floating). The tasks of this circuit component are: - amplification of ECG signals - lead selection (lead selector) - identification and reporting of electrode defects - identification and reporting of patient lead connection - digitization and serialization of ECG data - potential separation of the application component from the remaining circuit components (floating) - floating component power supply - ECG trigger - pacing-pulse detection There are two of these circuit components on this PCB. Once for the ECG via paddles, once for the ECG via patient cable. A second unit provides floating separation and the power supply for SPO2. A further circuit component controls high-voltage generation for the Defi shock. There is a high-voltage capacitor on this PCB. The functions are as follows : - safety control during charging and shock release (1st path : hardware) - controlling storage operation and energy release, independent of the CPU - controlling the high-voltage generator - elimination of interference in the operating elements in the Defi electrodes - conversion of the voltage and current signals into a frequency to measure energy - activation and control of the high-voltage transformer - generation of the emergency cutoff signal in the event of inadmissibly high voltage - measurement of the high voltage on the primary winding of the high-voltage transformer 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 15 - rectification of the high voltage - protection of the high-voltage diode - discharging the storage capacitor as a safety precaution - measurement of the high voltage on the storage capacitor - energy delivery via the high-voltage relay A further unit organizes the entire instrument´s power supply. This is provided by the built-in battery, the power supply unit or, optionally, from an external battery (e.g., ambulance power supply system). It has the following tasks: - switching instrument on/off - automatic cutoff when battery voltage is too low - monitoring the “charge battery” threshold - power source selection: battery or power supply system - charging the built-in battery by a special circuit independent of how high the supply voltage is PCB Digital The PCB Digital is equipped with the microcontroller, which controls the entire instrument. It comprises a Motorola 68332 microcontroller, RAM, EPROM, EEPROM, watchdog and I/O ports. It has the following functions: - safety control during charging and shock release (2nd path : software) - displaying the ECG and text on the LC screen (delete bar procedure) - processing the curves and texts for the printer controller for output onto paper - 50 / 60-Hz filter (software) - alarm management Circuit component display : - graphics controller to control the display, which ensures screen refresh - display RAM - generation of voltages for the LCD ( LCD power supply ) - generation of high voltage for background illumination - Pal for chip select generation for display - contrast adjustment Circuit component real-time clock : - real-time clock with lithium battery buffer and integrated quartz crystal - Pal for chip select generation for clock Circuit component 1-channel recorder : - single-chip microcontroller to output data at thermal-array printhead - monitoring printhead temperature - motor control for paper transport - switches off motor in the event of overload or underload 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 16 - generation of power supply voltages for the recorder - processing of all signals for the printer microcontroller Further circuit components on the PCB are : - generation of 5 V from 12 V via an integrated switching controller, short-circuit-proof and protected against overvoltage by Transzorb diodes - sound generator, frequency controlled by SW - RS-232 interface, protected against overvoltage by Transzorb diodes.

The new components are reported automatically in the software configuration. After restarting CardioServ recognizes the new components. This is important in the case of SpO2 and Pacemaker. Further the Performance Check (see on Page 62) needs to be accomplished. Replacing PCB Digital The identification numbers 0000 and 1111 are stored in the Eeprom of the PCB Digital for CardioServ Manual and CardioServ VF, respectively. The replacement PCB always has the identification number 0000 stored in the Eeprom for CardioServ Manual. If during servicing the replacement PCB Digital is inserted into a CardioServ VF, when it is switched on the CardioServ is in the manual mode. The following combinations of keys are required to switch the CardioServ from manual to semi-automatic operation. 1. Press F1 and F5 keys simultaneously: The function Configuration appears on the screen. 2. Press F3 and F4 keys simultaneously: The function Key Test appears on the screen. 3. Press the Analysis key. 4. Press F3 and F4 keys simultaneously. The identification code for the CardioServ VF stored in the Eeprom of the PCB Digital is now 1111 and the CardioServ operates in the semi-automatic mode. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH 227 483 02-B SA(e)-98.05 CardioServ V.4 Servicing Instructions Page 22 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 23 4.

Furthermore, the 1-volt ECG signal is still available at this option socket input. With an incoming ECG signal this can be measured with the oscilloscope. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 66 10.5 Battery A battery charge check can only be performed in the battery service unit Part No. 101 128 01. This tests takes at least 2 hours, max. 3 hours. The service manual for the battery service unit can be ordered under Part No. 227 454 77. If no battery service unit is available, the battery should be replaced every 2 years. Battery Maintenance Proper maintenance of NiCd batteries is essential and considerably promotes their proper performance. Routine preventive maintenance should be carried out by qualified service technicians on a regular basis (recommended interval: 30 days). If batteries are repeatedly partially discharged, the resulting "memory effect" max dramaticaly reduce the battery capacity. This effect can be efficiently minimzied by regular conditioning. If the capacity of a relatively new battery is drastically reduced, the battery max be reconditioned by repeated charging and discharging. Monthly Battery Maintenance (Conditioning) and Checks 1. Disconnect CardioServ from the power line and discharge fully charged battery in the (SpO2 sensor not connecmonitoring mode. To do so, set energy selector switch to ted) and wait until device switches off. 2. Check how long it takes before battery is depleted. If the time is less than 1.8 hours, the battery is too old or improperly maintained and should be replaced. 3. Recharge the battery. This will take 16 hours. Rechargeable batteries require special maintenance and continued checks to assure they function in emergency situations. It is normal for batteries of this type to selfdischarge when not in use. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 67 11. Safety Analysis Test 11.1. General introduction The suggested Safety Analysis Tests refer to the international standard IEC 601-1. The tests are generally performed with Safety Testers, on most of them, the measuring circuits according IEC 601 are already implemented. The following is a general description of the tests to be performed. For the handling of your Safety Tester follow the user manual. The tests may be performed under normal ambient conditions of temperature, humidity and pressure and with line voltage. The leakage currents correspond to 110 % of rated voltage for the tested unit. Most Safety Testers take this into account, otherwise the measured values have to be calculated. 11.2 Recommended Test Equipment - Safety Tester for measurements according to IEC 601. Testing connector according to the following description. 11.3 Protective Earth Resistance Test The power cord is to be included in the protective earth resistance test. This test determines whether the device has a power ground fault. The protective earth resistance from power connector to any protective earth connected exposed conductive part is measured. Specs. of test circuit: AC current source 50 Hz/60 Hz of at least 10 A up to 25 A with limited output voltage of 6 V. If resistance is greater than 100 mOhm, the unit fails this test. 227 483 02-B SA(e)-98.05 Marquette Hellige GmbH CardioServ V.4 Servicing Instructions Page 68 11.3.1 Leakage Current Measurement To perform the suggested measurements, the unit under test has to be separated from any interconnection to a system.

Connect earth (0 V) to the corresponding contact of the terminal block (4.8-mm sleeve enclosed). Please use the enclosed adhesive fastening base and the cable tie to fix the connection cables. Observe the following points when connecting the mounting system: - the negative terminal of the ambulance power supply must be connected to earth, - the positive lead must be protected with a 10 Amp fuse (slow blow) and - the lead diameter must be adequate. * Replace the 4 rubber feet of CardioServ with the metal feet enclosed. When screwing down the metal feet, please note that they have a recess on one side for the screw head. * Use the appropriate type of screws for attachment of the metal feet: If the CardioServ unit is equipped with metal bushings, please use the fillister head screws DIN 912 M 4 x 12; if there is no metal bushing but only a hole, please use Plastite screws 4 x 16. * Please be sure to use the red feet (angular groove) at the bottom, i.e., on the side with the contacts. (See Fig. 2). * The mounting system has 4 bore holes both at the top and bottom edges, allowing it to be mounted to the ambulance in a vertical or horizontal position (take care that the mounting system is flush against the wall of ambulance; in the vertical position the wider part with the cable aperture must face down!) (see Fig. 1). unlock here red Figure 2 * If required, you may attach the enclosed rubber feet on top of the metal feet. * Mount the CardioServ by first inserting the feet at the bottom, then by introducing the feet at the top. bottom Figure 1 227 483 02-B SA(e)-98.05 * To remove the device press on the latches (top center).
